The Presidential Address. 75 It would indeed be a most interesting study in psychological evolution to compare some of the earliest with some of the later opinions on the Darwinian theory. This is a task which I commend to those who have time and opportunity for collecting materials for such a comparison. Now, in the peace following the strife, it seems perhaps a reversion to ancestral savagery to execute a war-dance over the prostrate bodies of the slain; but, for my own part, acknowledging that, as a youth, I fell into the ranks of Darwinism, I cannot but own that a recent perusal of some of these early attacks has afforded me considerable satisfaction. Looked at in the present state of knowledge it is seen that many of these criticisms were prompted by nothing else than the animus of bigotry, or were the ignorant vituperation of extreme specialism ; nor is it, perhaps, necessary to say that some of the loudest clamour was raised by those having no shadow of a claim of any kind to make themselves heard. Of these multifarious expressions of opinion the majority were, it is needless to state, devoid of value, and in many cases the critics, perhaps from an incapacity for handling the true weapons of scientific discussion, descended to personal aspersions upon Mr. Darwin's character. But, on the other hand, the views advanced were more ably handled by the larger-minded and more competent thinkers in the world of science. From these appeared some criticisms of real im- portance, which led Darwin, with that splendid candour which was part of his nature, to modify certain details of his theory in the later editions of the 'Origin.' In the meantime, in the quiet seclusion of his Kentish home, Darwin pursued his labours with "philosophic calm," answering his critics with gentleness, and turning a deaf ear to personalities, knowing that he had a great truth to proclaim to the world, and upheld by the knowledge that the leaders of biological science had become his disciples. In this country Sir Charles Lyell, the illustrious founder of Uniformitarian Geology, Dr. Hooker, Herbert Spencer, Prof. Huxley, and Sir John Lubbock, were among the first to give the weight of their support to the Darwinian hypothesis;
